A To all ywhom/t may concern.:

, particularly motorcycles., A-more specific object is to devise a clutch control that is actuated by the operators foot and that will remain in any position in which it is placed by the foot of the operator automatically. It is well known that the clutch is used in Y different states of engagement and that it is desirous of having a control by a pedal that will maintain the clutch in any degree of engagement. A further object is to make a rocker clutch control that can be operated by one foot, the toe rotating it in an anti-clockwise direction and the heel in a clockwise' direction. A further object is to make a rocker clutch control that is positive in its action, made of few and' simple parts, that can be readily assembled and disassembled; one that lends itself readily to multiple production, is positive in its action and easily applied to a standard vehicle or motorcycle. With these and other objects in view my invention has relation to certain novel features of construction and arrangement of parts as willbe hereinafter more fully -described, pointed out in the claims and illustrated in the drawings in which Fig. 1 is a side elevation of my device and Fig. 2 is a plan view of my device. Numeral 3 designates a bracket secured to the frame or other portion of the vehicle or motorcycle by a bolt `passing through the hole 4. Numeral 5 designates an arm extending longitudinally parallel to the frame and having the finger 6 formed thereon at its end and at right angles to it. A slot 7' 1s formed in the finger 6 and a hole 8 passes through the finger 6 as clearly shown in the dra-wing.V A second finger 9 is formed on the bracket 3 at 1() vand has a hole 11 passing therethrough. A mutilated cylinder 12 is formed integral with the end of the bracket 3 opposite the finger 6 with the external portion of its lateral surface removed. A coil spring 13 is secured in the mutilated cylinder 12 in a longitudinal position by means of the pin 14 which passes through the head of the mutilated cylinder 12 at 15. Numeral 16 designates va cam which Vis rotatively secured at the side of the finger 9 by means of the bolt 17 which passes through the hole 18 in the cam 16 and through the hole 11 in the finger 9. Normally the left side of the cam,

16 in F ig.- 1 rests or is supported against the coil spring13. Numeral 19 designates a lever rotatively secured in the finger '6 by means of the bolt y20 which passes through the hole 8 in' the finger 6 and through a hole inthe cam 19 itself pernoittingthe lever 19 to oscillate' in the slot 7 of the finger 6. Numeral 21 designates a rocker: arm 'of the shape best shown in Fig. 1 and having secured to it at its ends the heel and toe rests 22 and 23 which are conventionally in the position shown Vin Fig. 2, but which may be rotated against the coil springs 24 and 25. I claim no novelty in the heel and toe rests 22and 23 nor in their methods of attachment. through a portion of a circle in the event that the rider on a motorcycle should tip to one side to such an extent that they would come in contact with an external object or the ground, that they would notk be broken.

Formed integral with the rocker arm 21 is the lateral projection 26 which has formed the two clevises 27 and 28 thereon. Holes 29 and 30 are formed in the rocker arm 21 and corresponding holes are formed in the opposite arms of the clevises 27 and 28. Numerals 31 and 32 designate rollers which are rotatively secured in the clevises 27 and 28 by means of the bolts 33 and 34 which pass through the holes 29 and 3() in the rocker arm 21 and the holes in the clevises 27 and' 28. Numeralv 35 designates a bolt which passes through a hole 36 in the rocker arm 21 and through the hole 37 Vin the bracket 3. By means of this bolt the rocker arm 21 and the bracket 3 are assembled into operative positions. The free end of the bolt 35 is secured conveniently to the frame. The'lateral projection 26 is of such length and pro-r portion that when the rocker arm 21 and the bracket- 3 are assembled that the cams 16 and 19 will ride on the rollers 31 and 32. Numeral 38 designates a reach rodvwhich is broken off at its righty end in Fig. 1 andV has a'clevis 39 formed at its inner end'. Numeral 4.0` designates a bolt which passes through holes 42. in` the clevis 39 and through holes 43 in the external end of the cam 19. Several such holes as 43 are pro- They are simply made to rotate ies vdedin order to enable the reach rod 38 Y to be adjusted vertically. Thereachrod connects to the clutch whichA I have not K shown and which is no part of rny invention, .Y The tension in the reach rod38 which is very great in the average clutch on arnotor-VV cycle niust be counterbalanc'ed or counteracted and I have provided' the coil spring 13 Vfor that purpose. 'It Will .be Seen that when the toe rest 22 of the rocker ar1n 21 is rotated in an anticlockwise direction by f pressing` on thetoe rest 22 With the toe that pletely engaged or in the completely' disengaged positions of the clutch terrnediate position.

Aor in any in- What I claim and meanto secure by Letters latent is I Y 1 I y Y l. ln combination with a bracket having a earn and a lever revolubly securedthereto7 a reach rod revolubly secured to said lever, a rocker ar'm rollers revolubly vsecured to said :rocker arrnin such position that theyV are in contact with the inner faces of said cani andl'ever7 a coiled spring secured t0 said bracket'in Contact With said cam.
